What Is Broad-Leaf Water Sprite Plant?
Ceratopteris cornuta is an aquatic fern, also known as broad-leaf water sprite, that is recognized by its broad, fan-like leaves.

Broad-Leaf Water Sprite Plant Facts
Ceratopteris cornuta is considered a low-light fern that needs minimal attention as long there is minor care with periodic trimming and fertilization.
This fern produces branching runners that off-shoot from its stems which can be either uprooted and replanted into a new area in your aquarium or snipped off the top of the water’s surface for further maintenance.
The leaves of Ceratopteris cornuta are oval-shaped, fanning out from pointed tips, making a radius of approximately two inches.
Although they are thin in texture, they are strong, which keeps them from tearing easily.
The leaves of this fern also come in a variety of shades of green, including a light green hue at the tips and a dark green hue at the base.
Ceratopteris cornuta can be found in shallow, still ponds, lakes, and marshes.
In its native habitat, this fern generally receives low to medium light amounts in waters with a temperature ranging from 70°F to 85°F.
The Water Sprite Plant is an exceptionally tolerant fern. This plant will do remarkably well in all pH ranges, except highly alkaline.
However, for optimal growth, it prefers a neutral or basic pH between 6.5 and 7.
Keep in mind that a pH level of 7 is considered neutral. Meanwhile, a pH below 7 is acidic and a pH above 7 is alkaline.
This type of fern will do great in a variety of vivarium types.
When deciding if rather or not to use Broad-Leaf Water Sprite in a particular type of enclosure, Be sure to go with setups that have fully aquatic areas.
Here are recommended vivariums Ceratopteris cornuta will do well in:
- Paludariums – Half aquatic/ half terrain-based enclosure.
- Ripariums – Mostly aquatic-based enclosures with some terrain features present.
- Aquarium – Fully aquatic-based enclosure with little to no dry terrain.
In a vivarium, this fern should be planted where the roots are submerged and the leaves are floating on the surface of the water to ensure healthy growth for the plant.
As previously stated, this fern works well as a midground or background accent, so plant it near the rear of the tank where the light levels are low to moderate.
Floating ferns are generally substrate less plants. The Broad-Leaf Water Sprite Plant is not an exception when it comes to this.
Ceratopteris cornuta does not need an aquatic substrate, as it only needs its roots submerged for the fern’s overall health.
If planted, simply make sure to only cover the roots and keep the crown exposed.
Low and medium amounts of light are best for this fern, although it can thrive in any form of lighting because of its tolerant nature.
To get the most benefit from the lighting, attach a light as close as possible to the surface of the water.
This will enable the plant to receive light directly from its leaves that are floating at the top.
When setting up lighting inside of an aquarium, LED lights will work extremely well.
Try to go for colors that resemble a bright day. Avoid any type of light that has high levels of UV rays.

These runners should be planted directly in the substrate if possible or held down with rocks if necessary.
How to grow
As previously mentioned, Ceratopteris cornuta can be propagated by taking and replanting the off-shoots that it produces.
To ensure that the off-shoots take root and begin to grow, place them in the nutrient-rich substrate and ensure that light, temperature, and ph are all at optimum levels.
Watering for this fern is relatively easy, as long as the water level does not exceed the height of the fern’s roots.
The water must be nutrient-rich and free from pollutants. Aim for a neutral ph and a temperature of the 70°F to 85°F.
